IoT has greatly influenced the smart cities and helps it in making a sustainable environment in it. The major objectives of smart and sustainable societies are to provide livability, renewal, and a sustainable environment for human life [1]}. Smart and sustainable cities are connected by heterogeneous devices like computers, traffic lights, roadside units, healthcare units, and smart homes. One of the important aspects of smart and connected cities [2]}, [3]} is to make societies sustainable. The connected objects in such types of societies are to provide a resource-efficient environment, ensure safety, healthy living-hood, and provide a smart transport system [4]}, [5]}. The IoT applications in the smart transport system depend on the VDTN paradigm of networking [6]}. In VDTN, the vehicles are connected with roadside units, lights, and other vehicles. For IoT applications to work in VDTN efficiently the connected objects need to be cooperative and forward data within a network [7]}. However, some of the nodes in the VDTN have selfish behavior. Many researchers have addressed the issue of selfishness in it. The selfish behavior of the nodes degrades the performance of the network [8]}, [9]}. Incentive-based mechanisms encourage the selfish nodes to simulate and share its resources for cooperation in the network [10]}. Incentive schemes are credit-based, reputation-based, game-theory and barter systems. All the cooperative nodes are rewarded for showing cooperation by the credit-based approach in the network. This reward will be used by the nodes in the network for their purpose later on in the election process.
